Exterior Wall / Window Water Penetration Testing

Need to find a leak? Using non-detructive test methods to precisley determine where the moisture entry is taking place by simulating wind and rain combined with interior wall testing probes.

Air Tightness Testing . . . view video

Also called a blower door test, both the air tightness, rated in air changes per hour and equivalent leakage area can be calculated using a large fan and air pressure manometer gauge. This can be particularly useful in moisture tests and energy evaluations.

Infrared Thermography Scanning . . . view video

You would think we can actually see inside the walls, but what we really see is the heat signature of various components. Missing insulation, radiant floor heating tubes, and moisture are just some of the things we test. Combined with a blower door test we can pinpoint air leakage paths.
